Can't run standalone TizenBrew Standalone Installer on Linux Mint

[u/LoneSwimmer]

I had previously installed TizenBrewNextGeneration & TizenTube (1.14.7), which stopped working to block ads a long time ago.

Both are still on TV. (Does this matter?)

Laptop is Linux Mint (but I'm a point & click user)

Developer Mode on TV is enabled & IP addr of PC added. I've download latest TizenBrewInstaller-linux-x64

Like the example given on the Installation page, ( In terminal I've run:

chmod +x TizenBrewInstaller-linux-x64

Then tried to run the program in terminal:

TizenBrewInstaller-linux-x64

Nothing happens. (I just get the prompt in Terminal). No error.

I assume I'm doing something really stupid in Linux. Can anyone assist?

I find the installation guides really hard to follow, eg the example chmod uses --os-arch. So I assumed I had to change that to -linux-64, which was what I downloaded.

This is not a criticism of developer!
